This paper hypothesizes that long-term structural and policy factors endogenous to the energy sector also play a relevant role. Through a case study of three major gas markets – UK, US, and EU – the paper finds that countries characterized by abundant domestic production are less exposed to price volatility as they benefit from lower market uncertainty and asset specificity. This encourages energy firms to outsource production and rely on more flexible and shorter-term contracts. A structural condition of abundance supported by liberalization policies and a developed infrastructure network allows energy firms to easily switch suppliers or buyers without being exposed to the opportunistic behavior of the commercial counterparty, increasing market competition and reducing prices. By contrast, import-dependent countries face greater uncertainty and asset specificity, as supplies and prices are not guaranteed and they heavily depend from trends in international markets. In this context, the contractual and structural flexibility brought about by liberalization policies may expose to further insecurity of supply and volatility of prices, as exporters are contractually disengaged from commitments on volumes and prices. In periods of international scarcity, they may redirect supplies to importers that offer a premium in price. This suggests that import-dependent countries could reduce their exposure to price volatility (i) by increasing domestic production (ii) while envisaging the coexistence of contractual models based on both market competition and vertical integration, to take advantage from low spot prices in periods of international abundance and contain the surge in periods of scarcity.","PeriodicalId":38329,"journal":{"name":"Competition and Regulation in Network Industries","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43040053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these overall positive effects could be also driven by the incumbent’s incentive to exclude competition within the liberalised markets. Such a situation occurred on the Prague-Ostrava line where liberalisation brought lower prices and an increase in quality. However, it also brought multiple accusations by both the Czech competition authority and the European Commission of the state-owned incumbent, České dráhy, that it had engaged in predatory pricing. This paper then assesses whether the price decreases within this line were driven by actual competition or by predatory behaviour of České dráhy by analysing the position of České dráhy. The aim of this paper therefore is to assess the real market power of the Czech state incumbent, České dráhy, on the Prague-Ostrava line. To achieve this aim, we used unique data we had gathered from our previous research (such as price development, market shares and customer behaviour). Our results then show that it is unlikely that České dráhy could have acted independently of its competitors and customers, which indicates that it could not have had a dominant position.","PeriodicalId":38329,"journal":{"name":"Competition and Regulation in Network Industries","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43850526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data sharing shall close information gaps in the predominant economy and, hence, form the backbone of the transition to a CE. As part of the recent legislative proposals from the EC, “digital product passports” (‘DPPs’) are expected to constitute one-stop shops for such data and information delivery. The principal idea of DPPs is to provide product information to interested stakeholders within and outside the product value chain. However, many challenges arise with DPPs, in particular how to reconcile a broad (if no ‘open’) access to data while preserving the (legally protected) interests of certain actors, and the lack of trust concerning data use and quality between the actors. Our hypothesis are (i.) that such challenges are related to the absence of an appropriate (data) governance model for DPPs and (ii.) that data governance as a main concern within the data economy agenda could inform the regulation and operationalisation of DPPs. We analyse the – lack of - (data) governance of DPPs, both in the literature and in the recent legislative proposals from the EC. We find that data governance is significantly overlooked or considered only from a pure technological perspective (techno-solutionism), which is likely to jeopardise DPPs. As both a confirmation and a way forward, we establish connections to data governance as per the data economy agenda. In turn, the analysis of DPPs governance informs the general discussion on data governance.","PeriodicalId":38329,"journal":{"name":"Competition and Regulation in Network Industries","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42944377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the full potential of digital advancements can only be achieved with the widespread adoption of digital technologies, which depends on the capable delivery of information and communication technologies (ICT) and their effective usability. Despite increased Internet penetration rates in Turkey in recent years, disparities in Internet adoption continue to persist. This study investigates whether and to what extent key demographic and socioeconomic factors are associated with the first-level digital divide in Turkey. The phenomenon is discussed in three aspects: device access, Internet access, and Internet use. The findings demonstrate that the vast majority of people in Turkey have Internet-enabled devices, mainly smartphones. Age, income, and education are significant predictors of Internet access. However, even when access is available, large disparities exist among gender, age, income, education, and employment groups in terms of Internet use. Moreover, our findings reveal significant regional differences in both Internet access and use. The results point to the need for a more coherent vision on ICT policies such that the need for demand-side programs are intended to stimulate broadband adoption widely by those groups. This paper provides useful pointers that can facilitate further academic research and structural decisions among policy-makers, by emphasizing the high-priority target groups.","PeriodicalId":38329,"journal":{"name":"Competition and Regulation in Network Industries","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41553753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aimed at facilitating the re-use and sharing of data in and between the private and public sectors, the DGA introduces regulation for a newly emerging type of digital platforms – the so-called “providers of data intermediation services”. In order to offer their services on the market, providers will have to submit to a prior notification procedure and show compliance with several conditions placed on their economic activities. The regulation of data intermediaries is intended to increase their trustworthiness and ensure the competitiveness of the markets in which they operate. Recent experiences with digital platforms have shown the potential of intermediaries to organise and facilitate markets. At the same time, digital platforms pose undeniable risks to their users and markets at large. Against this backdrop, the role of data intermediaries as envisioned by the DGA must be examined carefully before turning to the question whether the DGA can achieve competitive and trustworthy data sharing through registered third parties. This paper intends to shed light on these and other issues by examining, in-depth, the chapter in the DGA dedicated to data intermediaries (Art. 10–15) from a legal, policy and competition economics perspective. In particular, this paper explores how the experiences made with large-scale digital platforms have shaped the DGA. Thereby, this paper aims to contribute towards a holistic understanding of these provisions as a basis for an informed discussion on the legal framework and on possible alternatives.","PeriodicalId":38329,"journal":{"name":"Competition and Regulation in Network Industries","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43974703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal of this paper is to develop a network economic foundation for 5G-based network slicing based on a generalization of the concept of virtual networks combining a required sequence of virtual networks in order to fulfill the necessities of smart network industries. The key concept to analyze the economic incentives of the different actors involved is the well-established concept of opportunity costs of usage of scarce network resources. The allocation problem of traffic service providers fundamentally differs from the allocation problem of virtual network providers. Whereas interoperability and interconnection between different virtual networks are not standardized significant standardization efforts via network slicing can be observed in particular from the perspective of end-to-end QoS guarantees. 5G-based big data use cases with cross-border challenges for network slicing, and the subsequent interoperability of virtual networks, enable tremendous potential for innovation in smart physical infrastructures. The 5G-based European Future Railway Mobile Communication System and cross-border oriented, 5G-based connected, cooperative, and automated mobility applications are investigated with a large and open set of heterogeneous use cases requiring cross-border standardization of QoS-differentiated network slices.","PeriodicalId":38329,"journal":{"name":"Competition and Regulation in Network Industries","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47051874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A case of great interest in the rail sector is Italy, where on-track competition in the high-speed segment has been in place for nearly ten years. The paper aims at answering the question whether—and how much—incumbent’s prices are affected when competition starts on a route previously in monopoly. The case is the start of operations on the Turin–Milan–Venice route, where Italo entered in May 2018. Adopting a difference-in-difference approach, we check if Trenitalia changed the price strategy on the route before and after the entry, with respect to two control groups. The addition of placebo tests allows us to understand the ranges of significance of the results and to estimate the noise level of the estimates. Our findings suggest that the start of competition led to lower prices in the short-medium period. In the specific case, the Milano–Venezia route saw Trenitalia’s prices reduced by 21–26% (±2–5%) in a time span of 84–140 days after Italo’s entry and for advanced bookings from 2 to 10 days. Last-day prices remain unchanged, while early bookings are reduced by just 9%. This price reduction does not remain stable in the longer term, when other effects add up and blur the effect of the entry. Nevertheless, we keep observing a smaller, ∼15%, but still negative prices change.","PeriodicalId":38329,"journal":{"name":"Competition and Regulation in Network Industries","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47464928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This kind of competition has developed substantially in the EU during the past decade. There have been major entries into the national main lines in Italy, Austria, the Czech Republic, and Sweden. These entries have been very popular with passengers and rail ridership has gone up substantially. However, there have also been costs to these entries. The operations of the new entrants are diminishing economies of density, leading to higher unit costs. Further challenges include cherry-picking behaviour, scarce infrastructure capacity, tariff disintegration, and long-term sustainability. The major question is whether the social benefits outweigh the costs. This paper aims to review emerging evidence in the field of open access entries and approaches to their regulation. The scope of this paper is open access passenger rail entries in Europe after 2000 with a particular emphasis on the major entries that took place in Italy, Austria, the Czech Republic, and Sweden after 2011. The contribution of this article to the existing literature is threefold. Firstly, it provides an up-to-date review of open access entries in Europe. Secondly, it combines the results of simulation studies with empirical evidence to provide an overview of market impacts. Lastly, it reviews the spectrum of regulatory approaches.","PeriodicalId":38329,"journal":{"name":"Competition and Regulation in Network Industries","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45230567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
